Question 1097635
area is 84m^2  the length is 5+w   width is w  what are the length and width of rectangle
<pre>It doesn't make sense to form a quadratic for this. All you need is a set of factors of 84 that DIFFER by 5. 
This set is: 12 and 7. As the width is shorter, it MUST be 7 m. Can you tell what the length is?
That's it!! Nothing COMPLEX and/or CONFUSING!
